Abstract: 601,838. Arc-rupturing in switches. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 5, 1945, No. 25940. Convention date, Oct. 10, 1944. [Class 38 (v)] In a circuit-breaker such as that described in Specification 565,823, the arc runner 3 for the moving contact, has secured to it diverging magnetic flanges 1, 2 which tend to maintain the arc midway between them, so preventing burning of the insulating arc-shoot plates 5, 6.

Title: Combined disc and shoe brake
IPC: F16D55/14
Filed: 1956-08-28
Abstract: 799,157. Combined disc and drum brakes. BENDIX AVIATION CORPORATION. Aug. 28, 1956 [Sept. 14, 1955], No. 26268/56. Class 103 (1). In a combined disc and drum brake of the kind in which composite braking devices are used such that by axial movement apart of friction elements 24 to engage the inner radial sides of drum or rotor 42, the rotation thereof produces radial movement of shoe member 26 about anchor posts 18 to engage arcuate lining segments 56 with the axial surface of the rotor, the shoes 26 have curved pivot ends 62 on their webs, which slidably engage hardened anchorplates 66. Such free floating movement enables any preferred wedging angle for the anchor to be used, thus making it possible to select the desired anchor ratio for the arcuate shoes. The friction elements 24 are spread apart by fluid pressure-operated pistons 36 in cylinders 24 but hand-actuated means, as shown particularly in Fig. 2, comprises articulated levers 108 operated by a cable and operative on additional frictional elements 104 and 106.

Title: Improvements in or relating to inductance charging circuits
Inventor: BEST JOHN EDWARD
IPC: H03K4/28
Filed: 1953-09-24
Abstract: 758,931. Converting. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 24, 1954 [Sept. 24, 1953], No. 26274/53. Class 38 (2). [Also in Group XL (c)] The invention relates to circuits for generating a D.C. voltage, of the type comprising an inductor 3 connected effectively in series with a valve 2 arranged to be rendered intermittently conductive to cause current to flow from a supply into the inductor, a capacitor 4 being connected across the combination and a unilaterally conductive device 5 being connected in shunt with the valve whereby when the valve is non-conductive and after a resonant reversal of the inductor current has taken place the capacitor is charged through the unilateral conductive device by the inductor. According to the invention an impedance 11 is connected in series with the source of supply to the valve whereby the capacitor may charge to a higher voltage than that of the supply. The circuit shown generates a saw-tooth current in the inductor 3 and an E.H.T. voltage is obtained from a rectifier 7. The potential across capacitor 4 has a parabolic variation and may be chosen such that the current waveform in the inductor 3 which is the deflector coil of a cathode-ray tube compensates for the distortion due to the flatness of the tube face. In Fig. 1 (not shown) the auto-transformer is omitted and the device 5 is connected directly to the anode. The impedance 6 takes the form of a diode or an inductor. It is stated that 600 V. may be developed across capacitor 4 (for use in an external circuit) from a supply of 200 V.

Title: Improvements in chocks for aircraft or other wheels
IPC: B64F1/16
Filed: 1946-09-06
Abstract: 616,423. Wheel chocks. PYRENE CO., Ltd., and MACDONALD, I. G. Sept. 6, 1946, No. 26897. [Class 103 (i)] A wheel chock, particularly for aircraft wheels comprises a separate ramp and shoe which can be interlinked in latch fashion or disengaged at will, the shoe, when in use and interlinked to the ramp, lying to the rear of the ramp and being engaged by the wheel. The ramp is preferably collapsable and the arrangement may be such that collapsing of the ramp automatically disengages it from the shoe. In one form, Figs. 1, 3 and 4, the ramp comprises a wheel - contacting member 3 formed by a U- shaped rod spanned by inverted channel members 8 and pivoted by pins 7 to a base 4 constituted by a U-shaped plate having upstanding peripheral flanges 5. The member 3 is raised and lowered by toggle links 11 and 16 having a common pivot 15, the pivot pins 12 of the upper links 11 also passing through the side arms of a pedal 14. The links 16 are pivoted to the head 18 of a T-shaped member whose stem 19 is slidable in one arm 21 of a three-armed lever 22 pivoted on the base, and a spring 20 normally maintains the member 3 in a collapsed position. The second arm 26 of the lever is adapted to engage a claw 27 on the head 18 to lock the toggle links when the member 3 is raised by depression of the pedal. The 'third arm 28 of the lever carries a roller 29 which is normally engaged in a depression 30 between two cams 31 formed on a lever 32 pivoted about a vertical axis on the base. To collapse the member 3, the lever 32 is rocked by pulling on a chain 34 from either side, thus causing one or other cam to rock the lever 22 thereby compressing the spring 20 and disengaging the arm 26 from the claw. The lever 32 carries two studs 54 which are engaged by the pedal 14 to centralize the lever when the member 3 is being raised. The shoe 2 is formed by a cast plate 36 and is wedge-shaped at its rear edge. At its forward edge 42, the plate is formed with two holes 39 receiving lugs 40 secured to the base 4, and when the member 3 is raised its down-turned ends 41 engage over the edge 42 to lock the shoe to the ramp. The shoe may be constructed in sections to render it flexible, and be made of or covered by non- metallic material. In a modification, Fig. 7, the shoe 43 is made of flexible material such as rubber-reinforced canvas and is wedge-shaped at its rear edge 44. A pair of loops 45 engaged by the ends 41 of the member 3 are attached at the forward edge. Three metal plates 46 of arcuate cross-section are secured to the underside of the shoe and have teeth 47 which are engaged with or driven into the ground by the weight of the wheel to increase the resistance to slipping. Holes 51 and grooves 52 are provided to break the suction and facilitate removal of the shoe from wet ground.

The division between the instep block and the main body of the last is near the sole surface of the last, so that the main part of the last may be readily removed from the shoe. When the main body is hinged, the instep block forms a strut to maintain the last extended. Preferably, a fourth block 4 is interposed between the heel portion of the last and the instep block. The instep block has a bore 23 cut away at an angle at 23a and co-operating with a dowel pin 19.
